Doesn't the president spend Christmas at the White House to ensure as many as possible SS can spend the holiday at home with their families?
This is one reason the SS love the Bush family so much! He treats them like equals, he serves them whenever he can as much as they serve him; unlike some who shall remain nameless who treated the SS like plantation help.
Now that you mention it I do believe they have stayed at the White House for the actual holiday and then usually head out to Texas afterwards????
